Ineed to know which pair of lines best emphasize the theme that it is important to be kind no matter the circumstance?

the answer is both an appeal to ethos and logos (if that's what your question options were)

martians or other types of aliens represent a unique fear as opposed to zombies. vampires and other types of monsters.   in most sci-fi stories, aliens come from other worlds and have different or more advanced technology.   abductions and experimentation on human bodies that involve these technologies, or the use of these technologies against human beings and the use of unknown "powers", are a type of fear that's different from that of other types of monsters.  

i'd say the answer is nuisance. i hope i .
